SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 555,722, dated March 3, 1896.

Application filed May 22, 1893. Serial No. 475,059. (No model.)

To all whom it may concern:

Be it known that I, TnoMAsCoRsCADEN, of New Britain, in the county of Hartford and State of Connecticut, have invented anew Improvement in Shelf-Brackets, (Case E;) and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, Clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

' Figure 1, a view, in side elevation, of a bracket constructed in accordance with my invention;'Fig. 2, a plan view thereof; Fig. 3, a broken view of the bracket in rear elevation.

My invention relates to an improved wrought-metal shelf-bracket,the object being to produce a simple, light, and strong bracket adapted to be produced at a low cost, as scrap metal may be utilized in its manufacture, and as its parts are very readily assembled.

With these ends in view my invention consists in a wrought-metal shelf-bracket composed of three independently-formed members or parts and having certain details of construction, as will be hereinafter described and pointed out in the claim.

As shown in the drawings, the flat body portion A of the bracket has two straight edges and a, located at a right angle to each other, a concaved outer edge a and a triangular opening of. If desired, however, the edge a may be cut away on the broken lines a a leaving a simple triangular body portion. To the said edges a and a of the body portion I permanently affix a sheetmetal shelf-plate G and a sheet-metal wallplate H in any approved manner. As herein shown, the edge a of the body portion is constructed with lugs a a which are entered into openings g g, located in the shelf-plate, while the edge a of the body portion is constructed with lugs a a", which are entered into openings h it formed in the wall-plate.

' The said lugs may be upset, or may be secured in the said openings by brazing, welding, or otherwise.

The construction thus described I do not broadly claim in this application, my invention herein relating to positively connecting the meeting edges of the wall and shelf plates for giving the bracket additional strength. As shown in the said figures of the drawings, the meeting ends of the said plates are formed with tongues g and grooves h, which are constructed and interlocked in the ordinary manner for dovetailing the ends of light wooden boxes together, with the exception that the outer ends of the tongues are riveted down to form a positive connection between the parts thus united.

As the union of separate pieces by dovetailing is, generally speaking, known, it is thought further description of it will not be necessary.

A positive connection is thus formed between the meeting ends of the plates, which gives additional strength to the bracket, besides enabling the parts of the same to be assembled very readily.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The herein-described wrought-metal shelfbracket, comprising a fiat body portion having two straight edges located at a right angle to each other, and sheet-metal wall and shelf plates permanently applied to the said edges, and having their meeting ends constructed with tongues and grooves which dovetail together, the tongues being secured in place to form a positive connection between the two plates, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
